Virtual private networks (VPNs) are a technology for connecting to the resources inside a secured local network from another network. VPNs are commonly deployed by corporations, schools, and other institutions so their users can access
local network resources when not on campus.

There are numerous systems for securing VPN connections, including some that rely on secure certificates and other schemes to ensure that only authorized users can connect. You must obtain the security details from your network administrator to configure VPN access from your phone.

Working with secure certificates

If your organization’s VPN access relies on secure certificates, you must obtain the certificates and store them in your phone’s secure credential storage, before you can configure VPN access on your phone.

If your network administrator instructs you download the certificates from a web site, you’ll be prompted to set a password for the credential storage when you download the certificates. If your network administrator has you obtain the
certificates in some other way, you will need to use the Security & location settings to set a password for the credential storage first.To add a VPN
